To use the "oracle-rdbms-server-12cR1-preinstall" package to perform all your prerequisite setup, issue the following command.

# yum install oracle-rdbms-server-12cR1-preinstall -y

Once it's completed successfully then follow below steps.

1. Set the password for the "oracle" user.

passwd oracle

2. Update the "/etc/hosts" file as follows.

127.0.0.1 localhost.localdomain localhost

# Public

192.168.56.101 kamesh4tad-rac1.localdomain kamesh4tad-rac1

192.168.56.102 kamesh4tad-rac2.localdomain kamesh4tad-rac2

# Private

192.168.1.101 kamesh4tad-rac1-priv.localdomain kamesh4tad-rac1-priv

192.168.1.102 kamesh4tad-rac2-priv.localdomain kamesh4tad-rac2-priv

# Virtual

192.168.56.103 kamesh4tad-rac1-vip.localdomain kamesh4tad-rac1-vip

192.168.56.104 kamesh4tad-rac2-vip.localdomain kamesh4tad-rac2-vip

# SCAN

#192.168.56.105 kamesh4tad-scan.localdomain kamesh4tad-scan

3. Edit "/etc/resolv.conf" file and include nameserver entry if not exist already.

#domain localdomain search localdomain nameserver 192.168.56.1

4. Edit "/etc/sysconfig/network-scripts/ifcfg-eth0" file, making the following change. This will take effect after the next restart.

ONBOOT=no 5. With this in place and the DNS configured the SCAN address is being resolved to all three IP addresses.

# nslookup kamesh4tad-scan Server: 192.168.56.1 Address: 192.168.56.1#53 Name: kamesh4tad-scan.localdomain Address: 192.168.56.105 Name: kamesh4tad-scan.localdomain Address: 192.168.56.106

Name: kamesh4tad-scan.localdomain Address: 192.168.56.107 #

6. Edit "/etc/security/limits.d/90-nproc.conf"

# From * soft nproc 1024 # To this * - nproc 16384

7. Edit the "/etc/selinux/config" file and update it as follows

SELINUX=permissive

8. Do the following to disable the firewall if it's enabled

# service iptables stop # chkconfig iptables off

9. To deconfigure NTP do the following

# service ntpd stop Shutting down ntpd: [ OK ] # chkconfig ntpd off # mv /etc/ntp.conf /etc/ntp.conf.orig # rm /var/run/ntpd.pid

10. Add the "-x" option into the following line in the "/etc/sysconfig/ntpd" file, if your RAC is going to be permanently connected to your main network

OPTIONS="-x -u ntp:ntp -p /var/run/ntpd.pid"

11. Then restart NTP.

# service ntpd restart

12. Create the directories in which the Oracle software will be installed.

mkdir -p /u01/app/12.1.0.1/grid mkdir -p /u01/app/oracle/product/12.1.0.1/db_1 chown -R oracle:oinstall /u01 chmod -R 775 /u01/

13. Log in as the "oracle" user and add the following lines at the end of the "/home/oracle/.bash_profile" file.

# Oracle Settings export TMP=/tmp export TMPDIR=$TMP export ORACLE_HOSTNAME=kamesh4tad-rac1.localdomain export ORACLE_UNQNAME=CDBRAC export ORACLE_BASE=/u01/app/oracle export GRID_HOME=/u01/app/12.1.0.1/grid

export DB_HOME=$ORACLE_BASE/product/12.1.0.1/db_1 export ORACLE_HOME=$DB_HOME export ORACLE_SID=cdbrac1 export ORACLE_TERM=xterm export BASE_PATH=/usr/sbin:$PATH export PATH=$ORACLE_HOME/bin:$BASE_PATH export LD_LIBRARY_PATH=$ORACLE_HOME/lib:/lib:/usr/lib export CLASSPATH=$ORACLE_HOME/JRE:$ORACLE_HOME/jlib:$ORACLE_HOME/rdbms/jlib alias grid_env='. /home/oracle/grid_env' alias db_env='. /home/oracle/db_env' Create a file called "/home/oracle/grid_env" with the following contents. export ORACLE_SID=+ASM1 export ORACLE_HOME=$GRID_HOME export PATH=$ORACLE_HOME/bin:$BASE_PATH export LD_LIBRARY_PATH=$ORACLE_HOME/lib:/lib:/usr/lib export CLASSPATH=$ORACLE_HOME/JRE:$ORACLE_HOME/jlib:$ORACLE_HOME/rdbms/jlib

14. Create a file called "/home/oracle/db_env" with the following contents.

export ORACLE_SID=cdbrac1 export ORACLE_HOME=$DB_HOME export PATH=$ORACLE_HOME/bin:$BASE_PATH export LD_LIBRARY_PATH=$ORACLE_HOME/lib:/lib:/usr/lib export CLASSPATH=$ORACLE_HOME/JRE:$ORACLE_HOME/jlib:$ORACLE_HOME/rdbms/jlib

15. Reboot the VM at this point to make sure all the changes have taken effect.

Install Guest Additions 1. Click on the "Devices > Install Guest Additions" menu option at the top of the VM screen and run auto-run 2. Add the "oracle" user into the "vboxsf" group so it has access to shared drives.

# usermod -G vboxsf,dba oracle # id oracle uid=54321(oracle) gid=54321(oinstall) groups=54321(oinstall),54322(dba),54323(vboxsf) #

3. Create a shared folder (Devices > Shared Folders) on the virtual machine, pointing to the directory on the host where the Oracle software was unzipped(C:\Share folder in my laptop). Check the "Auto-mount" and "Make Permanent" options before clicking the "OK" button.

Create the directory in windows for Node 2 and clone the hard disk. So my directory structure is like

Host: kamesh4tad-rac1 files will be in kamesh4tad-rac1 folder Host: kamesh4tad-rac2 files will be in kamesh4tad-rac2 folder Shared storage will be at kamesh4tad-rac folder

As shown in screenshot as below

Shutdown the machine kamesh4tad-rac1

4. Create ASM Shared Disks for Grid Infrastructure

1. On your laptop/Desktop, create 4 sharable virtual disks and associate them as virtual media using the following commands. You can pick a different location, but make sure they are outside the existing VM directory.

cd C:\VirtualBox\kamesh4tad-rac

2. Create the disks and associate them with VirtualBox as virtual media.

VBoxManage createhd --filename asm1.vdi --size 5120 --format VDI --variant Fixed VBoxManage createhd --filename asm2.vdi --size 5120 --format VDI --variant Fixed VBoxManage createhd --filename asm3.vdi --size 5120 --format VDI --variant Fixed VBoxManage createhd --filename asm4.vdi --size 5120 --format VDI --variant Fixed

3. Connect them to the VM.

VBoxManage storageattach kamesh4tad-rac1 --storagectl "SATA" --port 1 --device 0 --type hdd \ --medium asm1.vdi --mtype shareable VBoxManage storageattach kamesh4tad-rac1 --storagectl "SATA" --port 2 --device 0 --type hdd \ --medium asm2.vdi --mtype shareable VBoxManage storageattach kamesh4tad-rac1 --storagectl "SATA" --port 3 --device 0 --type hdd \ --medium asm3.vdi --mtype shareable VBoxManage storageattach kamesh4tad-rac1 --storagectl "SATA" --port 4 --device 0 --type hdd \ --medium asm4.vdi --mtype shareable

4. Now make them shareable.

VBoxManage modifyhd asm1.vdi --type shareable VBoxManage modifyhd asm2.vdi --type shareable VBoxManage modifyhd asm3.vdi --type shareable VBoxManage modifyhd asm4.vdi --type shareable

5. Start the "kamesh4tad-rac1" virtual machine by clicking the "Start" button on the toolbar and login as root user

# cd /dev

# ls sd*

sda sda1 sda2 sdb sdc sdd sde

6. Use the "fdisk" command to partition the disks sdb, sdc, sdd and sde.

The following output shows the expected fdisk output for the sdb disk.

# fdisk /dev/sdb

Device contains neither a valid DOS partition table, nor Sun, SGI or OSF disklabel Building a new DOS disklabel with disk identifier 0x62be91cf. Changes will remain in memory only, until you decide to write them.

After that, of course, the previous content won't be recoverable. Warning: invalid flag 0x0000 of partition table 4 will be corrected by w(rite) WARNING: DOS-compatible mode is deprecated. It's strongly recommended to switch off the mode (command 'c') and change display units to sectors (command 'u'). Command (m for help): n Command action e extended p primary partition (1-4) p Partition number (1-4): 1 First cylinder (1-652, default 1): Using default value 1 Last cylinder, +cylinders or +size{K,M,G} (1-652, default 652): Using default value 652 Command (m for help): w The partition table has been altered! Calling ioctl() to re-read partition table. Syncing disks. #

In each case, the sequence of answers is "n", "p", "1", "Enter", "Enter" and "w".

7. Once all the disks are partitioned, the results can be seen by repeating the previous "ls" command.

# cd /dev # ls sd* sda sda1 sda2 sdb sdb1 sdc sdc1 sdd sdd1 sde sde1 #

8. Add the following to the "/etc/scsi_id.config" file to configure SCSI devices as trusted. Create the file if it doesn't already exist.

options=-g

9. The SCSI ID of my disks are displayed below.

[root@kamesh4tad dev]# /sbin/scsi_id -g -u -d /dev/sdb 1ATA_VBOX_HARDDISK_VBbf99c520-ebe26574 [root@kamesh4tad dev]# /sbin/scsi_id -g -u -d /dev/sdc 1ATA_VBOX_HARDDISK_VB80aac8fd-eb083e92 [root@kamesh4tad dev]# /sbin/scsi_id -g -u -d /dev/sdd 1ATA_VBOX_HARDDISK_VB422d9712-9f1778ff [root@kamesh4tad dev]# /sbin/scsi_id -g -u -d /dev/sde 1ATA_VBOX_HARDDISK_VB871b9955-e01a9a56

10. Using these values, edit the "/etc/udev/rules.d/99-oracle-asmdevices.rules" file adding the following 4 entries. All parameters for a single entry must be on the same line.

KERNEL=="sd?1", BUS=="scsi", PROGRAM=="/sbin/scsi_id -g -u -d /dev/$parent", RESULT=="1ATA_VBOX_HARDDISK_VBbf99c520-ebe26574", NAME="asm-disk1", OWNER="oracle", GROUP="dba", MODE="0660"

KERNEL=="sd?1", BUS=="scsi", PROGRAM=="/sbin/scsi_id -g -u -d /dev/$parent", RESULT=="1ATA_VBOX_HARDDISK_VB80aac8fd-eb083e92", NAME="asm-disk2", OWNER="oracle", GROUP="dba", MODE="0660"

KERNEL=="sd?1", BUS=="scsi", PROGRAM=="/sbin/scsi_id -g -u -d /dev/$parent", RESULT=="1ATA_VBOX_HARDDISK_VB422d9712-9f1778ff", NAME="asm-disk3", OWNER="oracle", GROUP="dba", MODE="0660"

KERNEL=="sd?1", BUS=="scsi", PROGRAM=="/sbin/scsi_id -g -u -d /dev/$parent", RESULT=="1ATA_VBOX_HARDDISK_VB871b9955-e01a9a56", NAME="asm-disk4", OWNER="oracle", GROUP="dba", MODE="0660"

11. Load updated block device partition tables.

# /sbin/partprobe /dev/sdb1 # /sbin/partprobe /dev/sdc1 # /sbin/partprobe /dev/sdd1 # /sbin/partprobe /dev/sde1

12. Reload the UDEV rules and start UDEV. # /sbin/udevadm control --reload-rules # /sbin/start_udev

13. The ASM disks should now should be visible and have the correct ownership using the following command. If they are not visible, your UDEV configuration is incorrect and must be fixed before you proceed.

# ls -al /dev/asm* brw-rw---- 1 oracle dba 8, 17 Oct 12 14:39 /dev/asm-disk1 brw-rw---- 1 oracle dba 8, 33 Oct 12 14:38 /dev/asm-disk2 brw-rw---- 1 oracle dba 8, 49 Oct 12 14:39 /dev/asm-disk3 brw-rw---- 1 oracle dba 8, 65 Oct 12 14:39 /dev/asm-disk4 #

14. The shared disks are now configured for the grid infrastructure. Now shutdown the kamesh4tad-rac1 Node

5. Clone the Virtual Machine for second node – kamesh4tad-rac2

1. Shutdown the node 1 kamesh4tad-rac1 if not already done.

2. To clone the kamesh4tad-rac1 node, go to Machine > Clone or Ctrl+o

3. The New Virtual Machine should be kamesh4tad-rac2

To manually clone the VM.

1. Shut down the kamesh4tad-rac1 virtual machine using the following command.

# shutdown -h now

2. Manually clone the " kamesh4tad-rac1.vdi" disk using the following commands on the host server.

VBoxManage clonehd C:\VirtualBox\kamesh4tad-rac1\kamesh4tad-rac1.vdi C:\VirtualBox\kamesh4tad-rac2\kamesh4tad-rac2.vdi

3. Create the " kamesh4tad-rac2" virtual machine in VirtualBox in the same way as you did for " kamesh4tad-rac1", with the exception of using an existing " kamesh4tad-rac2.vdi" virtual hard drive

6. Modify the Virtual Machine – kamesh4tad-rac2

1. When the VM is created and before starting it, attach the shared disks to this VM.

cd /VirtualBox/kamesh4tad-rac

VBoxManage storageattach kamesh4tad-rac2 --storagectl "SATA" --port 1 --

device 0 --type hdd --medium asm1.vdi --mtype shareable

2. Start the "kamesh4tad-rac2" virtual machine by clicking the "Start" button on the toolbar.

3. Log in to the "kamesh4tad-rac2" virtual machine as the "root" user so we can reconfigure the network settings to match the following.

hostname: kamesh4tad-rac2.localdomain

eth0: DHCP (*Not* Connect Automatically)

eth1: IP=192.168.56.102, Subnet=255.255.255.0, Gateway=192.168.56.1,

DNS=192.168.56.1, Search=localdomain (Connect Automatically)

eth2: IP=192.168.1.102, Subnet=255.255.255.0, Gateway=<blank>, DNS=<blank>,

Search=<blank> (Connect Automatically)

4. Update the hostname in the "/etc/sysconfig/network" file.

NETWORKING=yes HOSTNAME=kamesh4tad-rac2.localdomain

5. Check the MAC address of each of the available network connections.

ifconfig -a | grep eth eth3 Link encap:Ethernet HWaddr 08:00:27:BE:87:11 eth4 Link encap:Ethernet HWaddr 08:00:27:C2:0A:0C

eth5 Link encap:Ethernet HWaddr 08:00:27:6F:A0:1C

6. Edit the "/etc/sysconfig/network-scripts/ifcfg-eth0" and update the value of eth3 HWADDR and deleting the UUID entry.

7. Edit the "/etc/sysconfig/network-scripts/ifcfg-eth1" and update the IPADDR and eth4 value of HWADDR settings as follows and deleting the UUID entry.

IPADDR=192.168.56.102

8. Edit the "/etc/sysconfig/network-scripts/ifcfg-eth2" and update the IPADDR and eth5 value of HWADDR settings as follows and deleting the UUID entry.

IPADDR=192.168.1.102

9. Edit the "/home/oracle/.bash_profile" file on the "kamesh4tad-rac2" node to correct the ORACLE_SID and ORACLE_HOSTNAME values.

export ORACLE_SID=cdbrac1 export ORACLE_HOSTNAME=kamesh4tad-rac2.localdomain Also, amend the ORACLE_SID setting in the "/home/oracle/db_env" and "/home/oracle/grid_env" files.

10. Now restart the kamesh4tad-rac2 and start the kamesh4tad-rac1, once they started do a network reachable test and also verify ASM disks availability
